"Knowing when to stop" is the fundamental prerequisite for accumulating great wealth. I just saw some KOLs saying they sold out completely, and it really struck a chord with me. You might think they are foolish, that the price will rise further, and so on. I remember meeting a few very smart and hardworking people on Twitter last year, and after chatting a few weeks ago, it turns out they have basically all exited the market. The reason is simple: they lost everything, and some even went into debt. As time goes on, this becomes even more evident. No matter how smart you are, if you don't know when to stop and just keep pushing forward, it leads to a dead end.
